Dear list, I have learned that one cannot make several async write requests, one after another, without waiting for the completion of each request, otherwise the bytes get merged and the messages will not make sense at the receiving side. I am correct assuming that, right? My doubt is if the same happens to async read requests. Does one have to wait a read request completes before issuing another? Will the bytes get merged too, if one does not wait before making another read request? Assuming things happen that way, one async request waiting for the completion of another earlier request, then one have serial I/O processing and if one wants to have things done in parallel, the simplest way would be having other(s) thread(s) reading and writting in the same I/O object. Is this correct? I hope I have made my doubts clear enough, and if it is not clear please say it and i will try to be more objective.
